Unused files appearing but reside in my library

Hey Christian,
I have all my music on a partition within my internal HD on Mac OS. I have an external SSD drive to hold my mixtapes. When I run "Find unused tracks, it keeps showing tracks that are already in my library. When I open them in Finder, they both have the same location.
Note that these files are 4k in size.

/Volumes/myDrive/MixTapes/._DJ Sensation - 90s Flashback Break.mp3
/Volumes/myDrive/MixTapes/._DJ Sensation - Blockbuster Party Megamix.mp3
/Volumes/myDrive/MixTapes/._DJ Sensation - Christmas Megamix.mp3
/Volumes/myDrive/MixTapes/._DJ Sensation - Classic House Megamix (Clean).mp3
/Volumes/myDrive/MixTapes/._DJ Sensation - Classic Rock (DJ Break Megamix) 126-152-84 (Clean).mp3

What can I do to resolve this?
I’ll be synching with Engine DJ and want to ensure the tracks appear there.
Thanks

The ._ files are hidden files that macOS uses and not the real files, hence the 4kb in size. If you have them in Lexicon, you should remove them because they can’t be played.
